v.Old English unbindan, “to free from binding,” from un- (2) + bind (v.). Cf. German entbinden, Dutch ontbinden. Literal and figurative senses both present in Old English. Suæ huæt ðu unbindes ofer eorðu bið unbunden in heofnum. [Lindisfarne Gospels, Matt. xvi:19] Unbound is from Old English unbunden, in literal sense. Figurative sense first attested late 14c.; of books from 1540s.
